Most people will worry about food and other necessary things first so the buyer pool will be reduced in uncertain times.
Income to a small degree effect prices. Basic RE value is affected by cost of building. The next factor is units available.
If people start being unable to meet payments it will increase the units for sale.
That is of course unless the political arena makes changes that allow borrowers to keep the home without making payments. I see that as a distinct possibility given the present
conditions. They will not want empty houses and homeless families.
